The 3D printed rocket engine is designed to work with bio-propane, a clean-burning, renewable fuel source that cuts carbon emissions.

Prime will make its maiden flight from Scotland in 2021, when it will carry an experimental payload from UK-based Surrey Satellite Technology Ltd (SSTL), which manufactures small satellites.

Graham Turnock, chief executive of the UK Space Agency, said: “Orbex’s new rocket design facility brings Britain one step closer to having its own domestic commercial launch capability. It firmly positions the UK as Europe’s frontrunner for those looking to Earth’s orbit and beyond for new opportunities.

“The new facility and future spaceport operations will help unlock vast economic and societal benefits not just in Scotland but right across the UK.”

The 2,000 square metre headquarters building in Forres will combine a rocket design and integration facility, an operations centre and executive offices.

UK Business Secretary Greg Clark said: “The plans for a spaceport in Sutherland have already attracted significant investment. Orbex’s rocket design facility will bring more than 100 new jobs to the Scottish Highlands region.

“The space sector is a great British success story. And we are working closely with industry to ensure we thrive in the commercial space age.

“New innovations, capabilities and expertise are driving significant growth, with the sector generating close to £15 billion in income each year.”

Chris Larmour, Orbex chief executive, said: “Since the announcement in July 2018 that we had been chosen to launch from the Sutherland spaceport, Orbex has been on an incredible journey, largely behind-the scenes.

“That is changing today, as we publicly reveal the company’s technical and commercial momentum.

“Not only do we have a full engineering prototype of the complete Stage 2 of the Prime rocket. But we also have a growing roster of customers hoping to be among the first to launch satellites from Scotland.”
